Insulated bag for beer keg

Abstract

An insulated bag having a hollow enclosing wall and one open and one covered end is disclosed. The enclosing wall and the covered end include a multilayered structure made of an inner layer of heat resistive material, an intermediate layer, filled with air or other flexible heat insulating material disposed over said inner layer, and an outer layer of a metalized polyethylene material disposed over said intermediate layer. The covered end includes a heat sealed removable disc that when removed provides an opening in said covered end.

I claim: 
     
       1. An insulated bag comprising: an enclosing wall having one open end and one covered end, said covered end having a removable portion, said portion when removed providing an opening in the covered end of said insulated bag;   said enclosing wall and the covered end including, a multilayered structure having an inner layer of heat resistive material, an intermediate layer filled with air or other flexible heat insulating material disposed over said inner layer, and an outer layer of a metalized polyethylene material disposed over said intermediate layer, said inner, intermediate and outer layer sealed together around the periphery of said removable portion.   
     
     
       2. The insulated bag of claim 1, wherein said intermediate layer further comprises a cellular structure containing entrapped bubbles of heat insulating gases. 
     
     
       3. The insulated bag of claim 2 wherein said heat insulating gas is air. 
     
     
       4. The insulated bag of claim 2 further comprising carrying handles for transportation. 
     
     
       5. The insulated bag of claim 1, wherein said removable portion is in the shape of a circular disc. 
     
     
       6. The insulated bag of claim 5, wherein said enclosing wall is a hollow cylinder. 
     
     
       7. The insulated bag of claim 1, wherein said intermediate layer has smaller dimensions than said inner and outer layers, so that only the edges of said inner and outer layer overlap. 
     
     
       8. The insulated bag of claim 1, wherein a beverage keg is positioned inside said insulated bag for insulation, the placement of said keg in said insulated bag creates a space between the outer wall of said keg and the inner wall of said insulated bag for receiving ice therein, said keg being positioned within said insulated bag such that the covered end covers the bottom of said keg and the open end of said bag is extended upwardly towards the top of said keg. 
     
     
       9. The insulated bag of claim 1, wherein a beverage keg is positioned inside said insulated bag for insulation, said insulated bag encloses said keg such that said covered end of said bag covers the top portion of said keg and the open end of said insulated bag is extended downwardly towards the bottom of said keg, said removable potion of said covered end being removed to define an opening in said covered end for facilitating attachment of a dispensing tap to the dispensing pipe of said keg.
